FIELD OF THE INVENTION

The invention relates to a casing intended for independent making of a<<Russian>> cigarette (papirosy)or the like smoking combination by asmoker or for bulk production.

BACKGROUND OF THE INVENTION

It is generally known that while smoking the consumer inhales the smokeof the smoking material. Smoke is a gas-dispersed system, aerosol,formed by the gaseous medium and particulate matters and liquidparticles, suspended in it, which are the result of incomplete burningof said smoking material.

The smoking material smoulders at constant pressure._During inhalation,the smoker creates a low-pressure zone at the place of smoke extractionin his or her mouth. As a result of the pressure differential, the flowof smoke exhibits laminar flow characteristics directed to the place ofits extraction by the consumer.

The combustion products or fumes of the materials being smoked containsignificant amounts of chemical elements and their compounds which areharmful to the human body.

A number of different filters aimed at the reduction of the chemicalconcentration in the smoke are known For this purpose, porous materialhaving high sorption properties expressed in high sorption activity andhigh sorption capacity are used in the filters. These filters are ableto sorb a significant part of the above harmful components of the smoke(envisaged by GB2347607).

High sorption properties of the tobacco products and accessories arereached by the usage of the reagents (envisaged by EP1128740) and thedifferent devices (envisaged by WO0209541), which have abilities toneutralize some harmful components of the fume.

However, a considerable number of consumers smoke wishing to obtainsmoke with its original taste and flavour, consequently with regularcomposition.

Among them there is an individual category of consumers givingpreference to the independent choice of filling materials comprisingtobacco blends and very often by cocktails of different tobacco blends.

A second category of consumers is forced against their normalinclinations, to resort to inhalations of the combusion products ofdifferent smoking blends for the purposes of medication anddisease-prevention. It is necessary to maintain the smoke compositionfor these consumers.

There are filters intended for maintenance of the original taste andflavour of the tobacco by means of ensuring the specified ratio of thefiltered and unfiltered smoke (envisaged by EP1093728).

It is apparent that any filter essentially changes the composition andsubsequently the taste and flavour of the smoke.

In spite of the fact that the sorption capability is a property of anybody, it is possible to achieve the maximum preservation of thecomposition, taste and flavour of the smoke by omitting such filters,reagents and devices.

There are many ways and products which make it possible for the smokerksto inhale the unfiltered smoke. However, each of them has certainimperfections along with the advantages.

Cigars and cigarillos are rather expensive and contain an amount of thesmoking material significantly exceeding the proportions of the standardcigarettes and may lead to the increase of their consumption.

When smoking filterless cigarettes, the smoker extracts the smokeimmediately from the smoking part which is why particles of thecombustion products may get into the smoker's mouth and the increasingtemperature of the outer surface of such a cigarette doesn't allowcomplete smoking of the portion of the smoking material. It reduces thesmoking comfort and increases the losses of the smoking material inwasted cigarette stubs even when using cigarette holders or standardsheets of perforated cigarette paper (envisaged by EP1378182).

In addition, many prepared tobacco products restrict the consumer inselection of the smoking material or force him or her to unecessarilypay for the unused contents when such contents are thrown away.

Consumption of the combustion products of a smoking mixture by means oftobacco pipes corresponds to the existing preferences and necessity.However, pipes are also rather expensive and are intended for repeateduse and thus they require proper care.

The aforesaid problems are solved by utilization of cigarettes rolled bythe smoker. However, these cigarettes have all the disadvantages of thefilterless cigarettes. Besides, rolling of the cigarettes by the smokeris a rather time-consuming, laborious process requiring certain skills.Even though there are known mechanical devices (such as disclosed inEP1374705 or EP1397054) which (noticeably facilitate this process, theydon't solve all the problems.

So called <<Russian>> cigarettes are used along with in addition to theabovementioned methods for the purpose of consumption of the unfilteredfumes or combustion products of smoking materials.

It is common knowledge that the <<Russian>> cigarette is one variety oftobacco product and comprises a casing incorporating a portion of thesmoking material. The mouthpiece of the <<Russian>> cigarette includesan empty mouthpiece and an empty envelope. The mouthpiece is a pipe madeof rather heavyweight mouthpiece paper. The envelope is a pipe made ofcigarette paper. It is linked to the mouthpiece overlapping it along thefull length or part of its length or by means of a connection element.The empty part of the envelope standing out of the borders of themouthpiece and connected to the cavity of the mouthpiece, intended forthe allocation of the smoking material, forms the smoking part of thecasing of the <<Russian>> cigarette. It is possible to install a filterinside the mouthpiece. The fumes of the smoking material coming out ofthe smoking part pass through the cavity of the mouthpiece and areextracted by the smoker from that end of the mouthpiece, which is moredistant from the portion of the smoking material.

The <<Russian>> cigarette has the following standard dimensions:diameter from 4 to 6 mm, length from 70 to 105 mm, including the lengthof the mouthpiece from 40 to 70 mm, length of the smoking part is from30 to 35 mm.

<<Russian>> cigarettes offer the following obvious advantages ascompared with the other of the methods and devices for the consumptionof unfiltered smoke.

In the first place, this disposable product is cheap andmaintenance-free.

In the second place, the standard <<Russian>> cigarette has a portion ofthe smoking material compatible to the same portion contained in thestandard cigarette. It doesn't provoke increase of the consumption ofthe smoking material.

In the third place, the smoker extracts the fumes out of the end of theempty mouthpiece discontiguous to the smoking part. The significantlength of the mouthpiece favours the cooling of the smoke. Thus themouthpiece itself gets heated only slightly. It increases the comfort offume extraction by the smoker and allows smoking of the portion of thesmoking material completely avoiding its wasted losses.

Tobacco and non-tobacco blends are used in the <<Russian>> cigarettes asa smoking material.

In spite of the available advantages, the industrial production of<<Russian>> cigarettes and application of their casings for thehome-made cigarettes is restricted. It is caused by several significantdeficiencies.

First of all, while making the <<Russian>> cigarettes it is difficult toprevent the particles of the smoking material from passing out of thesmoking part into the cavity of the mouthpiece and consequently into themouth of the smoker during smoking.

This is the reason why in extensive manufacturing, the smoking part ofthe mouthpiece of a <<Russian>> cigarette is filled with the smokingmaterial pressed in the form of a compact rod. In addition, in order toprevent portions of the smoking material into the cavity of themouthpiece, grooves with the teeth turned back into the cavity of thecigarette holder (for example cigarette manufacturer DE3518831) can bemade on the inner wall of the mouthpiece of the <<Russian>> cigarette.

However, while filling, storing, transporting and using the <<Russian>>cigarettes, the pressed smoking material becomes loosened). Regardlessof the presence of the aforesaid teeth, the particles of the smokingmaterial escape from the smoking part into the cavity of the mouthpieceand later on into the mouth of the smoker during smoking.

It is problematic for a smoker to make a <<Russian>> cigarette usingsuch a casing since the non-pressed smoking material gets spilledthrough the wide cavity of the mouthpiece.

Installation of a filter in the cavity of the mouthpiece of a<<Russian>> cigarette or application of the filtering mouthpiece (forexample smokers' article EP1163857) almost excludes the possibility ofgetting of the particles of the smoking material into the cavity of themouthpiece and into the mouth of the smoker during smoking. However, itis not acceptable for some of the above-mentioned categories ofconsumers.

Secondly, the envelope of a <<Russian>> cigarette is made of cigarettepaper which is a soft, yielding material. Hence there exists the problemof the smoking part of the casing of the <<Russian>> cigarette beingsubject to deformation before the smoking material is placed in it.Deformation of the part of the envelope intended for placing the smokingmaterial hampers the filling of the casing of a <<Russian>> cigarettewith the smoking material reducing the comfort of the consumer.

DISCLOSURE OF THE INVENTION

A first of object of the present invention is to provide a casing of a<<Russian>> cigarette or like smoking device, whose design impedes,without making significant changes in the composition of the smoke, thepenetration of the particles of the smoking material located in thesmoking part, into the cavity of the mouthpiece while filling the casingwith this smoking material, and into the smoker's mouth during smoking.A second object of the present invention is to provide a casing of a<<Russian>> cigarette whose design impedes the deformation of the partof the envelope intended for the allocation of the smoking materialbefore placing this smoking material.

A first object of the invention is the casing of a <<Russian>> cigarettehaving an empty mouthpiece and an empty envelope connected to it, atleast a part of the cavity of which is intended for the allocation ofthe smoking material characterized in that it incorporates a separatingpartition which is selectively penetrable by the smoke and installed sothat it is possible to separate at least a part of the cavity of themouthpiece from at least a part of the cavity of the casing intended forthe allocation of the smoking material as well as to overlap at least apart of the cross section of the cavity of the mouthpiece.

The pressed or non-pressed smoking material is located in the part ofthe cavity of the envelope of the offered casing of a<<Russian)>cigarette intended for it. By that the separating partitionbeing selectively penetrable for the smoke and installed so that it ispossible to detach at least a part of the cavity of the mouthpiece fromat least a part of the cavity of the envelope intended for theallocation of the smoking material and so that it is possible to overlapat least a part of the cross section of the cavity of the mouthpieceimpedes the penetration of the particles of the smoking material fromthe cavity of the envelope into the cavity of the mouthpieces.

While smoking a <<Russian>> cigarette, the separating partition beingselectively penetrable by the smoke, ensures penetration of the smokefrom the cavity of the envelope intended for receiving the smoking,material into the cavity of the mouthpiece.

At the same time, the separating partition being selectively penetrableby the smoke, is installed so that it is possible to separate at least apart of the cavity of the mouthpiece from at least a part of the cavityof the envelope intended for the allocation of the smoking material aswell as to overlap at least a part of the cross section of the cavity ofthe mouthpiece, and prevents the penetration of the particles of thesmoking materials from the cavity of the envelope intended for theallocation of the smoking material into the cavity of the mouthpiece andthe mouth of the smoker.

Success of the first object of the invention is achieved by managing thegenerally known information about the physical and chemical compositionof the fumes of the smoking materials, its physical and chemicalproperties and physical and chemical properties of the materials usedfor the production of the casing of a <<Russian>> cigarette.

The separating partition being selectively penetrable for the smoke andthe possibilities of its installation ensure the availability of theholes with the dimensions sufficient for the free passing of the gaseousmedium of the smoke and particles suspended in it from the cavity of theenvelope intended for allocation of the smoking material into the cavityof the mouthpiece.

Of course, certain quantity of the smoke components is being absorbed bythe partition as a result of the natural processes of the Brownianmotion, sedimentation, coagulation, capillary condensation, etc.However, absence of said filter, made of the material having highsorption properties, special reagents and devices for neutralization offume's components, ensure minor changes of the composition of the fumeof the smoking material.

Absence of the filter manufactured out of the material having highsorption capability and without application of the reagents increasingthis capability, ensures insignificant absorbing of the smoke componentsby the separating partition.

The separating partition being selectively penetrable by the smoke,prevents the particles of the smoking material from migrating from thecavity of the envelope into the cavity of the mouthpiece.

As a result of the natural processes, the internal surface of the emptymouthpiece also sorbs some amount of the smoke components. Themouthpieces, made of the material the sorption capability of which isnot so high, without application of the reagents increasing thiscapability ensures availability of the smoke with insignificantlychanged composition and consequently taste and flavour by the consumer.

The above separating partition being selectively penetrable by thesmoke, can be made in the form of a deformed part of the wall of theempty mouthpiece. Thus the selective penetrability of the separatingpartition for the smoke is ensured by the availability of the clearanceof the relevant size between the deformed and non-deformed parts of thewall of the empty cigarette holder. In addition to it, or alternatively,the selective penetrability of such partition by the smoke, can beensured by making of the perforations of the relevant size in thedeformed part of the wall of the empty mouthpiece.

As an alternative, the separating partition selectively penetrable bythe smoke, can be made in the form of perforated diaphragm installed inthe cavity of the mouthpiece or in the cavity of the envelope of thecasing of a <<Russian>> cigarette. The selective penetrability of suchseparating partition by the smoke is ensured by the perforations ofsuitable size.

Alternatively, the separating partition being selectively penetrable bythe smoke can be made in the form of a spiral insert installed in thecavity of the mouthpiece or in the cavity of the envelope of the casingof a <<Russian>> cigarette. In this case the selective penetrability ofthe separating partition by the smoke is ensured by the clearance of thecorresponding size between the convolutions.

The connection of the empty mouthpiece with the empty envelope in thecasing of a <<Russian>> cigarette can be ensured by different means. Forexample, by complete or partial overlapping of the mouthpiece by theenvelope or their butted joint by means of the connection element.

Besides, it is expedient to install a spacing insert in the casing of a<<Russian>> cigarette in the part of the cavity of the envelope intendedfor the allocation of the smoking material. It will impede thedeformation of this part of the envelope. This spacing insert isextracted before the allocation of the smoking material in the casing ofa <<Russian>> cigarette.

For the purpose of increasing the stability of the composition of thesmoke in the casing of a <<Russian>> cigarette suggested in the firstobject of invention it is advisable to manufacture the separatingpartition being selectively penetrable for the smoke and/or themouthpiece of the material having low sorption capability.

The second object of the present invention is a casing of a <<Russian>>cigarette having an empty mouthpiece and an empty envelope connected toit. This casing is characterized in that the length of the mouthpiece isat least equal to the length of the envelope, the envelope overlaps themouthpiece with all its length, the mouthpiece and the envelope areinstalled so that it is possible to move them relatively to each otheralong the common longitudinal axis.

The length of the mouth piece is not less than the length of theenvelope, and the mouthpiece is overlapped by all the length of theenvelope and is used as a spacing insert impeding the deformation of theenvelope including that part of it which forms the cavity intended forthe allocation of the smoking material. Installation of the mouthpieceand the envelope and providing the possibility of their mutualdisplacement along the common longitudinal axis makes it possible toform the cavity of the envelope as a result of this displacement. Theaforesaid cavity is intended for the allocation of the smoking material.

For the production of a <<Russian>> cigarette, the empty mouthpiece andthe empty envelope are displaceable relatively to each other along thecommon longitudinal axis. As a result, the envelope forms the cavityintended for the allocation of the smoking material. In this cavity thesmoking material is located and the resultant <<Russian>> cigarette maythen be smoked.

The success of the second object of invention is achieved by managementof the well-known information about the physical properties of thematerials used in the production of the casing of the so called<<Russian>> cigarettes.

The connection of the mouthpiece with the envelope is achieved byoverlapping the mouthpiece by the envelope. The mouthpiece having lengthat least equaling to the length of the envelope, is overlapped by allthe length of the envelope. The mouthpiece made of stiff mouthpiecepaper resists the deformation of the envelope made of softer and moreyielding cigarette paper. The mouthpiece and the envelope are installedso that it is possible to displace them relatively to each other alongthe common longitudinal axis, leading to the formation of the cavity ofthe envelope intended for the allocation of the smoking material.

The casing of a <<Russian>> cigarette or like smoking device in thesecond object of the invention may contain a separating partition beingselectively penetrable by the smoke, installed so that it is possible toseparate at least a part of the cavity of the mouthpiece from at least apart of the cavity of the envelope and so that it is possible to overlapat least a part of the cross section of the cavity of the mouthpiece.

The separating partition being selectively penetrable by the smoke maybe made in the form of a deformed part of the wall of the mouthpiece.Besides, or alternatively, the selective penetrability of such apartition for the smoke can be ensured by the perforations of suitablesize.

Alternatively, the separating partition being selectively penetrable bythe smoke can be made in the form of a perforated diaphragm installed inthe cavity of the mouthpiece or butt to it against the face of themouthpiece.

As an option, the separating partition being selectively penetrable bythe smoke can be made in the form of a spiral insert installed in thecavity of the mouthpiece or butt to it against the face of themouthpiece.

For the purpose of increase of the stability of the composition of thesmoke in the casing of a <<Russian>> cigarette as in the second objectof the invention it is advantageous to make a separating partition beingselectively penetrable by the smoke and/or mouthpiece of the materialhaving low sorption capability.

Alternatively, the casing of a <<Russian>> cigarette as in the secondobject of invention may incorporate any filter.

It is clear for those skilled in the art that any other additions and/ormore accurate definitions of the inventive design are possible withinthe limits restricted by the subject of invention.

BEST MODE CARRYING OUT THE INVENTION

Generally speaking, the casing of a <<Russian>> cigarette comprises anempty mouthpiece 1 and an empty envelope 2. Mouthpiece 1 is the supportpart of the casing.

Cavity 3 of the mouthpiece 1 is a channel for the passage of smokeduring smoking. Cavity 4 of the envelope 2 is linked to the cavity 3 ofthe mouthpiece 1 and is intended for the allocation of the selectedsmoking material.

A separating partition which is selectively penetrable by the smoke fromthe direction of the cavity 4 of the envelope 2 (FIG. 1, 2, 3, 4) and inthe embodiment is provided by a deformed part 5 of the wall of themouthpiece 1. There is a clearance 6 between the deformed part 5 of thewall of the mouthpiece 1 and non-deformed part of the wall of themouthpiece 1, the size of which is sufficient for letting the smoke flowfrom the cavity 4 of the envelope 2 into the cavity 3 of the mouthpiece1 during smoking. The deformed part 5 of the wall of the mouthpiece 1may be perforated (FIG. 4), with the size of the perforations 7 beingsufficient for the passage of smoke.

The separating partition being selectively penetratable by smokingalternatively, be made in the form of a perforated diaphragm 8 installedin the cavity 3 of the mouthpiece 1 (FIG. 5, 6). The separatingpartition being selectively penetrative by the smoke, may,alternatively, be made in the form of a spiral insert 9 installed in thecavity 3 of the mouthpiece 1 (FIG. 7, 8). The spiral insert 9 has aclearance 10 the size of which is sufficient for letting the smoke in.

It is advantageous to manufacture the empty mouthpiece 1, perforateddiaphragm 8 and spiral insert 9 of the same material using rather stiffmouthpiece paper. Such a material practically doesn't sorb thesubstances from the gaseous medium of the smoke and particles suspendedin it. As a consequence, the above elements of the casing of the<<Russian>> cigarette made of the mouthpiece paper have almost no effecton the composition of the smoke of the smoking material.

In any of the described embodiments of the casing of a <<Russian>>cigarette according to the inberntion, the connection of the emptymouthpiece 1 with the empty envelope 2 is ensured by the location of theempty mouthpiece 1 in the cavity of the envelope 2 with competeoverlapping of the mouthpiece 1 by the envelope 2. Other possibilitiesfor the aforesaid connection are envisaged. Thus, it is possible toconnect the empty mouthpiece 1 with the empty envelope 2 by means of theenvelope 2 partially overlapping of the mouthpiece 1 as shown in FIG. 9.In this case the empty envelope 2 tightly covers the empty mouthpiece 1along its length partially. Butt connection of the empty mouthpiece 1with the empty envelope 2 is also possible such as by means of theconnection element 11 (FIG. 10). In such a casing of <<Russian>>cigarettes according to the invention, the length of the cavity 4 of theempty envelope 2, intended for filling with the smoking material, arespecified by the manufacturer beforehand.

A spacing insert 12 (FIG. 11) for resisting the deformation of thecavity 4 of the envelope 2 during storage and transportation of thecasing before the location of the smoking material may be installed inany of the aforesaid embodiments in the cavity 4 of the envelope 2intended for filling with the smoking material.

In the first object of the invention, the casing of a <<Russian>>cigarette according to the invention having an empty mouthpiece 1 andthe empty envelope 2, the length of the mouthpiece 1 at least equals tothe length of the envelope 2 (FIG. 12). Empty mouthpiece 1 and emptyenvelope 2 are combined so that it is possible to move them relative toeach other along the common longitudinal axis. The empty mouthpiece 1may have a separating partition being selectively penetrable by thesmoke, made in the form of the deformed part 5 of its wall (FIG. 12)which may be perforated (FIG. 4). The separating partition beingselectively penetrative for the smoke, can be made in the form of theperforated diaphragm 8 (FIG. 13) or in the form of the spiral insert 9(FIG. 14).

The method of use of such a casing of a <<Russian>> cigarette accordingto the invention is as follows. Before filling with the smokingmaterial, a smoker moves the mouthpiece 1 and envelope 2 relative toeach other along the common longitudinal axis forming the cavity 4 ofthe envelope 2 intended for the allocation of the smoking material. Theextent of the above travel can vary.

Such a design of the mouthpiece 1 ensures protection of the emptyenvelope 2 against deformation and damage during storage andtransportation and prior to filling with smoking material and withoutapplication of any other additional elements. Besides, it allowsindependent adjustment of the size of the cavity 4 of the envelope 2 andconsequently adjustment of the amount of the smoking material located bymeans of moving the empty mouthpiece 1 and empty envelope 2.

Empty mouthpieces 1 are made by means of rolling appropriate sheetmaterials around the geometrical axis and overlapping such . Thedeformed part 5 of the wall of the mouthpiece 1 is formed individuallyon each mouthpiece 1. The perforations are made on the specified sectionbefore the rolling of the mouthpiece 1. The envelopes 2 are woundup onthe mouthpieces 1 or manufactured separately and connected with themouthpiece 1 by means of the connection element 11. The perforateddiaphragms 8 are made by means of stamping either as a whole with themouthpiece 1 before the rolling of the mouthpiece 1 or separately andare located in the cavity 3 of the mouthpiece 1 or in the cavity 4 ofthe envelope 2 butt against the mouthpiece 1. The spiral inserts 9 aremade by means of winding and cutting of the roll of the heavyweightpaper or cardboard also as separate parts and then are located in thecavity 3 of the mouthpiece 1 or in the cavity 4 of the envelope 2 buttagainst the mouthpiece 1. The spacing inserts 12 are made by means ofrolling the sheets of the heavyweight mouthpiece paper and are matchedwith the mouthpieces 1 before the winding of the envelopes 2.

Subsequently, the above casings of <<Russian>> cigarettes are assembledin complete sets, packed and transferred to a trading network.

Smokers fill the described casings of the <<Russian>> cigarettes withthe selected of prescribed smoking material and use ready cigarettes asintended in the generally accepted way.
